AMS1117-1.8
by Advanced Monolithic Systems
The AMS1117-1.8 is a fixed 1.8 V low-dropout linear regulator used to derive a regulated rail for digital and mixed-signal circuitry. This Advanced Monolithic Systems device is supplied as an SMD part in a four-connection SOT-223-style package, making it suitable for board-level power regulation where a linear topology is appropriate. The free KiCad download includes a 4-pin schematic symbol, the 4-pad SOT-223-4_L6.5-W3.5-P2.30-LS7.0-BR footprint, and a matching 3D model. The conversion has been used by 6 ProtoFlow engineers in real designs, providing practical verification beyond the source import. It can also be opened directly in ProtoFlow for placement and review.
